... the widely used human body model, charged-device model, and machine model, are based on this assumption. However, as this case study proves, passivated wafers and unpackaged dies are also susceptible to ESD damage. The authors explain that although this type of failure is difficult to diagnose, they were...

... that result from such grossly extended initial damage may cause EOS failure signatures in many cases, as shown in Fig. 2. One should also note that in case of real ESD, such a failure signature may appear as a consequence of subsequent overcurrent in operation but was originally caused by an ESD-induced gate...

... are focused on electrostatic discharge (ESD) damage on the GaN die, as ESD damage is the most common failure mode for GaN LEDs. Failing WLEDs are de-capped (removing silicone glue and phosphor with chemicals) to examine the burn mark caused by an ESD event. By optical inspection, a tiny crack near the P...

The PTEM image indicated that the damage occurred between two contacts that were farther apart and separated by a trench, but not between the nearest contacts. Such damage revealed the current path during...

... device can be caused to fail by an ESD event. Devices that withstand 4000 V are considered very robust. A common minimum expectation for ICs is a human body model damage threshold of more than 2200 V for any combination of two pins. Devices susceptible to damage by 1000 V or less require exceptional care...

The various failure modes and failure locations depend primarily on pulse parameters such as pulse amplitude, energy content, or rise and fall time of the pulse. For example, ESD protection structures can be activated by test pulses 3a and 3b, which...
